• E&M trunks interface to the system using the E&M trunk card in the peripheral cabinet. The card
can be configured for either 2-wire or 4-wire operation. Type 1 through Type V circuits are
supported.
• Direct Inward Dial and Tie trunks interface to the system through the DID/Loop Tie trunk card in
the peripheral cabinet.
IP Networking
IP Networking provides an integrated networking solution that allows voice and signaling data to be
transported over the existing LAN/WAN infrastructure between multiple 3300 ICPs. MSDN/DPNSS
features are supported over IP Networking.
Each 3300 ICP supports up to 2000 IP trunks allowing for a ’cluster’ of up to 80 3300 ICP systems to
work as a single integrated voice system. Each pair of 3300 ICP systems can be connected by up to
200 IP trunks.
Note: A Mitel Networks 3800 IP Trunking Gateway that adjuncts an SX-2000 or 3200 ICP cannot
be directly connected to a 3300 ICP. To support this configuration the 3300 ICP would also
require an adjunct 3800 IP Gateway.
ISDN (Integrated Services Digital Network)
ISDN Support
The Integrated Services Digital Network (ISDN) transmits voice, data, and video at high speeds.
ISDN services can be deployed and accessed at enterprise, department, and desktop levels by
adding the 3300 Universal NSU with PRI or the 3300 BRI NSU.
LAN traffic can also be carried over existing private or public digital network connections on Euro
ISDN, DASSII (public access) protocols, or even on a private MSDN/DPNSS network using ISDN
connections to a router.
ISDN Connectivity
ISDN access lets customers leverage the advantages of ISDN network services for both voice and
data applications, effectively improving performance and network resource management while
controlling costs.
The 3300 ICP supports multiple ISDN protocols and provides ISDN connectivity. The system
connects with the ISDN public network and data devices (such as routers, video conferencing
equipment, and servers) by using Primary Rate Interface (PRI) or Basic Rate Interface (BRI). ISDN
takes advantage of the following features to capture and control costs, analyze peak periods, and fine
tune network resources accordingly for both voice and data calls:
• ARS/LCR (Automatic Route Selection / Least Cost Routing)
• SMDR (Station Message Detail Recording)
• Min/Max Traffic Control
• Per Call Service Selection
• Limited Toll Restriction
• Trunk Diagnostics
• NFAS (Non-Facility Associated Signaling)
• Remote LAN Access.
